To @ZZ 'wiz/0m '25 may conoefm s Be it known hail, FRANK F. HALL, a citizen oi' lihe United States, :mil residen o' Little Falls, in the county of Herkimer and State of New York, did invent certain new and useful nnproveinents in 'lherniostatic Regulators for Heating" Apparatus, of which the following is a Specification.

My invention relates io tlierniostotio 'ro gulators for heaing apparatui, and it has for its primary object, the irovision of a device of this character which ia simple and of inexpensive conelauciion and one which is very sensitive liereoro qui li in action under Changing temperature.

Another ohj ect of my invention is the pio vision of Simple and eifoeiive, adjusting means whereby rho regulator '11 ai" he aaljus'ie. to maintain any clesired Liegi-ee ol heat.

Anoher object of niv invoniou he production of a regulaingr device which, while adaptable, 'for rwulatiug the heat in various 1T forms, of stoves or heaters, is particular clesgned as an oquipu'ion of heaters poultry hroorling.

A weight 2O may be'A adjustably se- A the weight of the damper 18 and thus render the regulator more sensitive. By adjusting this weight the sensitiveness of the regulator may be controlled.

Secured to the supporting traine l1 is the controlling member hereinbet'ore referred to, said member being designated 2l, and coinprisinga regulator bar E22 and a fulcruin head 2?) to which said bar is riveted or other- 'wise secured. Said regulator bar is formed of tivo strips or' metal Q4, 25, of diierent eX- panding properties7 which strips lie in contact and are riveted together, as at 2G, or otl erwise suitably connected. The fulcrum head Q3 may be cast or otherwise fashioned to provide a tlat portion 27 for connection to said portion and a bifurcated segmental portion 28 and a pair of upstanding ears 29 between which is received the supporting fiancey ll, said ears being pivotally secured to said trame, as at 30.

ln the supporting frame ll directly above the segmental portion of the fulcrunrhead 23 is a tapped aperture 31 into which is threaded an adjusting screw 33 provided with an annular groove 34E anda suitable head 35. Said segmental portion of the fulcruin head straddles said screw and engages the annular groove therein and 21s this segmental portion is at one side of plane passing through the pivot 30 of this controlling `member and the regulator bar at the other,

the adjusting of the screw causes said bar to flex one way or the other to assist or resist the action ot the heat thereagainst, consequently enabling the iiegulation of the heat to any desired temperature.

The heat acts to expand the metal strips constituting the regulator bar and by reason ot' one strip expanding more than the other, the bar becomes flexed. The movement thereof is imparted to the operating lever 14@ by a link 36 pivotally connected to both and extending through an opening' 37 in the supporting frame; the pivotal connection of said link to said lever being comparaw tively close to the fulorum point of the latter so that slight movement of the link caused hy the regulator bar will result in much greater movement of the outer end of said operating lever and consequently a considerable movement 0f the damper, so as to check or enliven the lire Within the heater, as the ease may be.

lt will be plain to those skilled in the art to which this invention appertains that where the draft opening in a heater is otherwise arranged than herein shovvn slight modification falling fully within the scope of my invention may be resorted to; also that other changes in minor details ofgconstruction and arrange-ment may be resorted to without departing from my invention or sacrifie-idg any of' the advantages thereof.

The operation of this invention will be plain from the foregoing description and further illumination thereof is not believed to be necessary. V

Having thus described my invention, what I claim is,-

l. ln conibination with a damper or the like ot a heater, a regulator comprising a support having a shield extending therefrom, a regulator bar formed of metals of dillerent expanding quality secured together througl'iout their length, said shield being situated between said regulator bar and said heater, a. fulcrum head secured to said regulator bar and having a bifurcated portici., an adjusting screw engaging said bifurcated portion and threadedinto said support, and connection between the opposite end of said regulator bar and the damper. A

2. In combination With a damper or the. like of heater, a regulator comprising a support secured to the heater and havingl a depending shield, a regulator bar lying in front of said shield, a 'u-lcrum head secured to one end of said regulator bar having a pair of upstanding ears straddlihg said support and being pivotally connected therewith and a bifurcated segmental portion, an. adjusting screw straddled by said bifurcated segmental portion and adjustably en` gaging into said support, and operative connection. between the opposite end of said I regulator bar and the damper.

3. In combination with a damper or the like of a heater, a regulator comprising a support secured to the heater and having an opening therethrough and an upstanding lug, a regulator bar formed of metals of different expanding qualities secured together and having oneend adjustablly securedyto:'q.Y saidsupport, a link pivotally secured to the opposite end of said regulator bar and 6X4 tending upvvardly through the opening in said support, an operating lever pivotally secured to the upstanding lug of said sulp-v port to which the opposite end of said link is pivotally secured, and an operating connection between .said lever and the damper.

4. In combination with a damper or the like of a heater, a regulator comprising a support secured to the heater and having a depending shield, an opening `inthe support near one end and an upstandin lug, a regulator bar underneath said support and outside of said shield, said regulator, bar havine1 one end adjustably secured tesaid support, an operating lever .pivotally secured at one end to said upstanding lug, a link passing through they opening in said support and having one end` pivotally secured to the free end of said regulator bar and. its other end,

ingr rod pivot-ally secured to the free end of and also wlth n, bifuioatod segmental porv tion. un adjusting screw piovided with an fuloruin head lniving;

annular groove to receive the segmental p0rton of said ulorum head, said adjusting screw being adapted to be thioaerl into o, xed object, and means Vof connection bletween said regulator bnr and the damper.
